Electrosurgery has been used in dentistry for several decades, but the technique is not widely practiced. This article briefly explains the principles of electrosurgery and attempts to clear up some misunderstandings about the healing of electrosurgical wounds. Clinical application of electrosurgery for the management of some common oral conditions is also described.
A case is presented in which a nasopalatine duct cyst was misdiagnosed. Its subsequent mismanagement was further compounded with improper endodontic therapy. It was finally managed by corrective endodontic and surgical therapy.
The cases of two patients with large cystlike periapical lesions are presented. The lesions formed as a result of trauma to the associated teeth. Following conservative nonsurgical endodontic treatment, there was complete resolution of the lesions. These results suggest that the largeness of a periapical lesion does not mandate its surgical removal and that even cystlike periapical lesions heal following conservative endodontic therapy.
Cutaneous sinus tract of dental origin is the most common among the many types of sinus tracts that are formed on the face and neck. Because these lesions are often diagnosed incorrectly, they are also treated ineffectively. Cases of cutaneous sinus tract on the chin and cheek are presented, and a simple way to diagnose this lesion is described. In both patients, the lesion was completely resolved following nonsurgical endodontic therapy.
